It will be noted that as Wneh iS Secured e rearwardly @Xtendng flight they swing away from each other the bow string bOeId 11- TWO leVelS, herein designated as bOW will be progressively tightened at an increasingly levers 12, are pivoted at their forward extremi- @pid raie so as to provide a follow-up action .'CeS l'SO tne iight board 11 in spaced apat Te on the arrow which will greatly assist in its pro- 100 lation, so that they may be brought to a parallel jegton. The new is Continuously propelled position as shown in Fig. 2. The rearward or free from the position 0f Fig. 2 mm1 the String reahes extremities of the bow levers 12 are connected by the position 0f Fig 1. This action is Similar to means O a bOW String 13. the usual action of a regulation bow.

The leVeYS 12 flle d'neted by Ineens 0f WO The initial impulse of the cords 14 swings the 105l flexible cords 14, there being one cord for each levers l2 outwardly beyond their dead-center of the levers. The cords 14 extend forwardly from positions so that springs 20 are brought into acthe levers through eye members 15 on the horition to overcome the initial inertia of the levers zontal member 10, and thence rearwardly to a 12 and swing them outwardly. The springs are connection at 17 to a ball tether 18. The ball not intended to project the arrow. The latter 110 depends for its velocity upon the force imparted to the golf ball 19 by the driver. The horizontal member 10 may, if desired, be provided with a handle 27 by means of which it may be rotated so as to change an angle of the flight board 11. The board can then be locked at any desired angle by means of a locking segment 28 so that the arrow will be projected on any desired trajectory.

It is desired to call particular attention to the fact that the direction of the arrows flight is controlled by the accuracy with which the golf ball is struck. For instance should the driver hook the ball so that its natural curve would be to the left the result would be that the right hand cord 14 will tighten in advance of the left hand cord causing the right hand lever to lie actuated ahead of the left hand lever. This causes the bow string 13 to swing the rear of the arrow to the right so that it will be projected to the left. A sliced drive would have the opposite effect and project theA arrow to the right. A straight, correct drive' will tighten both cords 14 simultaneously and project the arrow straight ahead.

I claim:

i. amusement device comprising: a flight board adaptedV to V"supportv an arrow; a ball; a flexible connection extending from `said ball to said flight board and adapted to project said arrow from the latter when said ball reaches the extremity of Said flexible connection.

2. An amusement device comprising: a flight board; a series of levers adapted to lie on, and hinged at their onek extremities to, said flight board; a bow lstring connecting the other extremities of said levers and arranged to receive an arrow positioned iipon said flight board; a ball; and a flexible connection between said ball and said levers so that the energy of said ball will be communicated to said levers when' said ball is struck to cause said bow string to project said arrow. l

3. A device for projecting an arrow in consequence of the flight of a ball comprising:y a flight member adapted to support said arrow; levers hinged at their one extremity to said flight member so that they may be brought in to parallel relation; a bowstring connecting the free extremities of said levers and varranged to engage said arrow; a cord extending from each of said levers to a common junction; and a tether between said ball and said junction so that the force of Astonping the flight of said ball will be communicated to said levers to project said ar- IW; I

4. A device for projecting an arrow in consequence of the flight of a ball comprising: a flight board adapted to Support said arrow; levers hinged at their one extremity to said flight board so that they may be brought in to parallel relation; a bow string connecting the free extremities of said levers and arranged to engage said arrow; a cord extending from each of said levers to a common junction; a tether between said ball and said junction so that the force of stopping the flightv of said ball will be communicated to said levers to project said arrow; and cord guide members arranged to guide the angle of pull of said cords on said levers.

y.5. YA device for projecting an arrow in consequence of the flight of a ball comprising: a flight member adapted to support said arrow; levers hinged at their one extremity to said flight member so that they may be brought in toy parallel relation; a bow string connecting the free extremities of said levers and arranged to engage said arrow;- a cord extending from each of said levers to a common junction; a tether bctween said ball and said junction so that the force of stopping the flight of said ball will be communicated to said levers to pro-ject said arrow; coil springs connected to said levers intermediate their extremities and each extending to a fixed attachment point; said attachment points being in alignment with the axis of said levers when the latter are in parallel position.

6. A device for project-ing an arrow in consequence of the flight of a ball comprising: an inclined flight member adapted to support said arrow; levers hinged at their one extremity to said flight member so that they may be brought in to parallel relation; a bow string connecting the free extremities of said levers and arranged to engagesaid arrow; a cord extending from each of said levers to a common junction; and a tether between said ball and said junction so that the force of Vstopping the flight of said ball will be communicated to said levers to project said arrow; and means for Varying the incline of said flight member. v

7. An amusement device comprising: a projectile; a guide member arranged to initially guide s`aid projectile;` meansl for projecting said projectile into free flight in the air; said' guide member directing the' initial direction of said flight; a ball; an operative connection between said ball and said projecting means so that when said ball is struck,rthe energy imparted to said ball will be communicated to said projecting means to impel saidprojectile on its free flight.
